the Schedule term-ea to in these Lottoxi mm and making part or the same.

Be it known that I, J n nes M. Ausrm, of'Georgetown, in the county ofPettis and State of Missouri, have invented a nenf'and improved BrickMachine; and I' do hereby declare that the following is a full, clear,and exact descriptionthereof, which will enable others skilledin the artto make and use the same,- reference being had to the accompanyingdrawing. forming part of this specification. 7

- This. invention relates to improvements in'briele,

machines, and consists in anarrangement of they mold-carriage. ona pairofflanged rollers at the rear, and a pair of plane -faced rollers at thefront,

the latter being connectedbyvertically-sloited plates on the-carriageand pins on the 'sidesof the rollers in such 11' way that the carriage,whiclrismovedin and out by the turning of thesliaft; of the front willbe very: accurately, guided bythe said boarrested ,at the proper time bythe pins coming against the bottoms of-the slots.

i- Theinvention also consists in the connection of the press-operatingdevices with thecaM-iage-operatin g dev'ices in such away that the'risingoi the press at the time of the'outward movement of the carriagewill always be insnred. p v The invention also consistsin theapplication to ''tlie grate, through which the clay is pressed, of dejtacliabie plates, with .holesthrough them for forcing 'the claythroriglnso that plates with larger or'sinallerholes may he used,according to whether the clay is thick Ol' thi|1,-th0 flow of which intothe molds varies I Y according to its consistency, which flow it is theoh- 1 jest-of this part of the'invention to regulate.

' -FigureIis a sectional elevation of my improved machine, taken on theline a: :r-of fig. 2.

- Figure 2 is a horizontal section on thi: line 3 3/ of fig; 1, withsomeparts broken out.

; Figure 3 is a section through thc'gra'te v of reference indicatecorresponding :B, theepressywhich may be of ordinary constructheflanges.

The outer end isarranged on the large plane-faced I, rollers 1*, ,andthe slotted flanges are arranged on the earrnige to project downward,one on the outer's'ide of eaehrolllr, snnglyagainstflio said side, andmom a pin, H, projecting from the wheel into the slot, shown in fig. 1.

Thegreater part of the weight of the carriage is borne by-these rollers,and the-motion is imparted by the turning oftho shaft I through themedium of the lever K, r olling thesa'id carriage back and forthmainlyby the frictional contact, but the slotted -plates "G and pins H preventany slipping other.

They also cause the stopping of the oarriage at the ,reqnired plaee,when moved either ivay, by the contact of thepinswith the bottoms of theslots.

The press-follower I is. suspended from theorosshead K workingon thevertical'gnides L, and the said cross-head is connected by the rods Mand bar N with the foot-lever O, for forcingthe follower down to v pressthe elay'thron'gh the grate P, into the mold-boxesl).

, Inorder to insure the risingof thefolloiver at the cnrved'rods R,pivoted to the {lamest S, with the rods Maud-the pins H, as shown, sothat the-pins lil'lOlilllg, .l ill(l61'tile 1;ods R, -which; aresuitably curved downward for the purpose, raisethemand thefollower-during the outwardn ovoment of the carriage.

The 'clay or mud varies" considerably at diii'erent times inconsistency; according toftho nat'ure oi the sand and the amount ofwater 'm'ixed'with it,"so that, with the gratings, of the same size,more clay will be forced into the molds at one time than at another.

I therefoleprovide the main grating Pvwith open-' lngsof the largestsize, to be used when the clay is stilf and flowsthe slowest; and -Iarrange the said grating-plate'with grooves or channels, in which-I mayslide other plates, '1, containing 'smalleropenings, for the clay to beplaced on the gratingP when the clay isof the character to run morefreely;

--Any number of these plates'l. may be'provided,

the holes being varied in size to suit any condition of the clay; r ,l g

The said plates are inserted through small openings through the frontside .of the mold-hex, coinciding with the grooves or channels in plate1.

Having thus described my invention, I I claim. as new and desire tosecure by Letters Patent 1. The combination of the press-follower, theoperating wheels 1*. of the cai'i-iage;.pins H, slotted plates K, andconnectingaodsM, substantially as G, levers specified. I r

i 2. The combinationwith the niold-box and-press ing oase of thegrate-bars or'plate 1!, and the detachable plates '1, the-saidplateshaving the holes. arranged in the order substantially as specified.
